Woodworking

• 1. Introduction

  ›

  Woodworking reaches back further than most people imagine. At Kalambo Falls in southern Africa, shaped sticks bearing notch marks were left behind around 476,000 years ago. That pushes the craft deep into a world before agriculture, before cities, before writing. The hands that made those sticks were not human in the way we are today; microwear analysis of Mousterian stone tools shows that Neanderthals worked wood long before our own species appeared.

  The questions that follow from those ancient notched sticks are worth sitting with. How did woodworking go from basic shaped branches to the mortise-and-tenon joints of ancient Egypt, the timber treatises of Rome, and eventually to Computer Numerical Control machines carving intricate shapes from flat stock? And what is it about wood specifically - not stone, not bone, not clay - that kept drawing human hands back to it across hundreds of thousands of years?

  What emerges from woodworking's long record is a craft that mirrors civilization itself. It supplied buildings, tools, transportation, and household goods. It produced coffins for pharaohs and spears for hunters. The story winds through ancient forests cleared to feed a growing Egypt, through a legendary Chinese craftsman whose teachings were supposedly preserved in a book written fifteen centuries after his death, and into galleries showing modern sculptures carved from rain tree. All of it starts with those notched sticks at Kalambo Falls.

• 2. The Oldest Tools

  Three spears cluster near the beginning of the woodworking record. The Clacton spearhead, found at Clacton-on-Sea in England, dates to around 400,000 years ago. The Schöningen spears from Germany are somewhat younger at around 300,000 years ago, and the same Schöningen site also yielded wooden tools that researchers believe were used for domestic work, including what appear to be awls. Then there is the Lehringen spear from northern Germany, set apart at around 120,000 years ago.

  Flint was the cutting edge of choice through much of this period. With flint tools, woodworkers of the Neolithic era shaped wooden vessels, and the Linear Pottery culture left evidence of carved wooden containers in wells at Kückhofen and Eythra. By the Bronze Age, craftspeople in northern Germany and Denmark were hollowing tree trunks into coffins and assembling wooden folding chairs.

  Iron Age woodworking left some of its finest traces at Fellbach-Schmieden in Germany, where detailed animal statues carved from wood have survived. Farther west, during the La Tene period, wooden idols carved for a sanctuary at the source of the Seine in France show how the craft had grown from hunting implements into objects of ceremony and belief.

• 3. Egypt's Craft in Wood

  ›

  Ancient Egyptian woodworkers operated under constraints that shaped everything they built. Deforestation in the Nile valley meant the region could not supply enough timber, so from the Second Dynasty onward Egypt imported wood - notably cedar, but also Aleppo pine, boxwood, and oak. Native acacias, local sycamore, and tamarisk supplemented these imports, but demand consistently outran what local forests could provide.

  The tools available to these craftspeople shifted over time. Copper served as the metal of choice for woodworking implements, then gave way to bronze after 2000 BC; iron working arrived only later. With copper and eventually bronze, woodworkers shaped axes, adzes, chisels, pull saws, and bow drills. Mortise and tenon joints appear in the record from the earliest Predynastic period, reinforced with pegs, dowels, and lashings of leather or cord. Animal glue was not adopted until the New Kingdom period, representing a significant change in how joints were secured.

  Ancient Egyptians invented the art of veneering, which allowed craftspeople to surface less valuable wood with a thin layer of finer material. Varnishes were applied for finishing, though the exact composition of those varnishes has not survived into the present record. The results of all this skill are preserved in the tombs: stools, chairs, tables, beds, and chests, plus the inner coffins that held the deceased. The quantity and quality of these surviving objects speak to how central woodworking was to Egyptian material life.

• 4. Rome and China

  ›

  Roman woodworking rarely survives in physical form, because wood decays and Rome burned more than once. The literary record filled the gap. Vitruvius devoted an entire chapter of his De architectura to timber, cataloguing the properties and uses of wood in Roman construction. Pliny, though not a botanist, gave over six books of his Natural History to trees and woody plants, tracking what the Romans knew about timber as a resource.

  The Romans used wood for buildings, transportation, tools, and household items, but also for pipes, dyes, waterproofing materials, and fuel. The breadth of that list - wood as infrastructure, chemistry, and warmth, not just furniture - suggests how deeply the material was woven into daily life and civil engineering alike.

  In China, the founding figures of the craft are named with unusual precision. Lu Ban and his wife Lady Yun are considered the progenitors of Chinese woodworking. Lu Ban came from the Spring and Autumn period, which ran from 771 to 476 BC. He is credited with introducing the plane and the chalk line to China. His supposed teachings were recorded in a book called the Lu Ban Jing, though scholars believe that text was written around 1,500 years after his death. The Lu Ban Jing is largely concerned with dimensions for building items such as flower pots, tables, and altars, and it gives extensive instructions on Feng Shui. Notably, the book says almost nothing about the intricate joinery, assembled without glue or nails, for which Chinese furniture became famous.

• 5. The Nature of Wood

  Wood falls into three broad categories: hardwoods from broadleaf trees, softwoods from coniferous trees, and manufactured materials such as plywood and MDF. The terms are botanical rather than descriptive of hardness; softwoods are not necessarily always softer than hardwoods, and the reverse is equally true.

  Softwoods come from gymnosperms - cone-bearing trees that stay green year round. They tend to be found in colder regions, and they are typically lighter, more vulnerable to pests and fungal attack, and more prone to shrinking and swelling as they dry. Their density generally falls in the range of 432-592 kg/m3. That lower density, however, gives them relatively high strength for their weight, and in the United States they are cheaper and more readily available than hardwoods. Western red cedar stands out among softwoods for its ability to resist wet conditions without rotting, making it a common choice for outdoor projects. Douglas fir is another familiar option, distinguished by a straight, pronounced grain with a red-brown tint, though it does not stain well and is usually painted.

  Hardwoods, botanically classified as angiosperms, shed their leaves annually and grow more slowly, which produces a higher density - around 1,041 kg/m3. Only about 200 of the many hardwood species are common enough and workable enough to be practically useful. Mahogany, known as one of the great furniture woods, carries a reddish-brown to deep-red tint but is rarely grown in sustainably managed forests. Maple displays chatoyance in the grain, a shimmering optical quality that sets it apart visually. American ash trees have been destroyed in large numbers by the Emerald Ash Borer, an invasive insect, a loss that has paradoxically made ash more available in some parts of North America.

  Hand tools, by definition, draw their power only from the hands holding them. Edged hand tools require periodic sharpening, accomplished with a sharpening jig and sharpening stone, or with sandpaper as a more recent alternative. Among the most common hand tools are clamps, which range from small C-clamps to large bar or strap clamps, and a vise - itself a type of clamp - which can be temporarily or permanently mounted. Chisels carry a long blade with a cutting edge for shaping wood. The claw hammer, capable of driving, prying, and pulling nails, is the most common hammer used in the craft.

  A hand plane smooths the surface of a workpiece. Squares mark angles: a try square handles 90-degree cuts, while a speed square can mark both 90- and 45-degree angles and any angle between 0 and 90 degrees along its long axis. Files and rasps both grind down wood, but they differ in their tooth size; rasps cut deeper and more aggressively, while files make finer, less harsh cuts.

  Power tools trade human muscle for an external energy source - a battery, motor, or wall outlet. The compound miter saw, also called a chop saw, makes precise crosscuts at adjustable angles. A table saw runs cuts along the grain, known as rip cuts, and can produce a beveled edge. A band saw handles both irregular cuts and cuts through material too thick for a table saw. A drum sander uses a wide rotating sandpaper drum to remove material as a board passes through; it operates on the same general principle as a thickness planer, but with sandpaper instead of blades. Among the notable craftspeople who have worked with this range of tools is George Nakashima, whose name appears alongside figures as varied as Alvar Aalto, Sam Maloof, and former United States President Jimmy Carter.

• 7. Modern Wood, Modern Art

  ›

  Computer Numerical Control machines changed what was possible in commercial woodworking. CNC wood routers can carve complicated and highly detailed shapes into flat stock, producing signs and art objects at production speeds with reduced waste. Power tools broadly have lowered the physical demands of the craft, compressing timelines that once required sustained manual effort.

  Handcrafted work has not disappeared under that pressure. Demand persists for furniture and objects made by hand, though consumer prices for such work are higher, a direct result of the gap between production rates by machine and by individual hands. The Windsor chair, for instance, involves green woodworking - shaping wood while it still holds its natural moisture, before drying is complete - a technique that sits outside what a CNC router can replicate.

  Modern wood carving now occupies space in art galleries and contemporary art exhibitions worldwide. It combines traditional techniques with current artistic styles and often reaches for unusual species - rain tree, for instance, or woods chosen specifically for distinctive textures - as a way of emphasizing the singularity of each piece. The carving woods that beginners reach for tend to be basswood, aspen, and butternut: basswood for its near-absent grain and notable softness, butternut for a deeper hue and easy workability. Black walnut, richer in color and grain, costs more but remains a consistent choice for carvers willing to pay for it.
